IMPROVEMENT IN sURGE-anLmvnRs ron cannes.v

The Schedule referred te in these Letters Patent and. making part of the same.

To all persons to whom these presents may come Be it known that I, JOHN J. EMERY, of Owls Head, ofthe countyof Knox, and. State of Maine, have invented a new and nsefnlGhain-Cable Safety-Apparatus or Mechanism; and I do hereby declare the same to be fully7 described in the following specification, and

represent-ed in the accompanying drawings, of which- Figure l is a top View, and

Figure 2, a longitudinal section of it as applied to y the bow and chain cable of' a Vessel.

Y suitable number of springs, S S.

These springs I arrange to slide on inclined rods av a, fixed in position upon the deck b of a vessel C.

The bridge B slides on the bars andagainst one end ',of each of the springs, and has the pawl pvoted to it,

so as to extend above it, inl manneras represented.-

\ Therefore, below the pawl is the bridge or rest B,

for the chain .to run on.

lThe springs at their other ends abut against a sta- -tionary shoulder-piece or vabntments, d d, secured to thedeck. l

The apparatus, as described,I arrangev on the deck, and forward ofthe windlass E, the chain cable, shown at F, being passed from the windlass to and between vthe pawl and the bed, and next through the hawse,

hole of the bow.

Ouf-dropping the pawl, so as to canse it to engage with the chain, a' strain on the latter, tending to draw the chain-ont through the hawse-hole, will be coun-1 teracted and eased bythe springs.

I am aware that it is not new to employ a spng to counteract a strain on a rope or rod, and, therefore, I make no, claim to the invention of this in the abstract; but i y l g What Ido claim as my invention, is-

The combination and arrangement of the chain-eable pawl A, the bridge B, the spring or springs S S,

-and their supporting rods a a, or mechanism in thewhole being to operate substantially as set forth. e
